2 invoices, same number, one paid, one not

flumpjumper

I have 2 customer invoices with the same number, which I thought was not possible. 

It has been paid, but as the duplicate hasn't been paid, customer is getting reminders. 

Checked, both have same invoice number, sent on different days to same customer. 

How can this be?

HI @janjac , @flumpjumper 

If you're using MYOB Business, the warnings for duplicate invoice numbers won't be displayed if you enter the same number accidentally. Therefore, please ensure the numbers are being double checked before saving the invoice.
